5) UGUI does not need to bind Colliders, and UI can automatically intercept events;
6) UGUI's Anchor is a relative parent object, and no advanced options are provided. Personally, uGUI's Anchor operation It is more convenient than NGUI;
7) UGUI does not have Atlas, and uses Sprite Packer;
8) UGUI's Navigation can be visualized in Scene;
